Download queue opens the whole directory tree

Nothing critical, but every time I open or reopen the download queue, it displays the WHOLE directory tree on the left side of the screen.

This can be pretty frustrating, since I usually download whole directories at once, which in turn my have subfolders, which in turn may have more subfolders etc. Thus checking whether or not a specific folder (especially so if the folder in question doesn't have subfolders, or only has few of them) has been completely downloaded may become difficult, since the directory tree is miles long.

Not that long ago I still used an older version of DC++ (can't remember version, VERY old in any case, maybe 0.4x?), and I don't remember this being an issue then.

Is there any way to set DC++ 0.75 up so that it doesn't open any of the subfolders? I've been combing the settings, but either it's not there, or I have just missed it every single time.

And to demonstrate what I mean:

this is what the directory tree looks like:

Download folder
  - Folder1
      - Folder1.1
      - Folder1.2
         - Folder1.2.1
      - Folder1.3
   - Folder2
      - Folder2.1
etc.

This is what I would like it to look like when I open the queue:

Download folder
   - Folder1
   - Folder2
   - Folder3
etc.
